IMPBOVED GNTRE-BOARD tlg rlgshule mmh tu in tigen @aos atent sur making mit nf its arme.

Be it known that I, FELIX DOMINY, of Penataquit, in the county of Su'olk, and State of New York, have invented a new and useful Improvement. in Centre-Board; and I do hereby declarevthat the following is a full, clear, and exact description thereof, which will enable others skilled in thc art to make and use-the same, reference being had to the accompanying drawings,vforming part of thisspecification, in which- Figure 1 is a. side view ofthe centre-board box, part being broken away to show the construction.`

Figureis a sectional view of 'the same, taken through the line z x, fig. 1.

Similar letters of reference indicate like parts.-

My invention has for its object to improve the construction of centre-boards, and make them more effective in operation; and it consists in the inclined slot formed in the forward part of. the centre-board, in combination `with the pivoting or suspensionpin, and in the combination of the curved rod or bar with the centre-board and with the centre-board box.

A is the centre-board, in the forward end of which is formed anfinclined slot, B, extending from about the middle of the forward part of the centre-boardto near its upper'forward corner. i Through the slot B passes the pin C, by'which the board is pivoted or suspended when in use. D is a roller placed in the slot B,^through which the pin C also passes, to prevent friction and the consequent wear as the board moves up and down upon the pin. To thd upper part of the forward end of the board A is attached a curved barl or rod, E, which passes out of the upper corner of the forward end of the centre-board box F, to raise and guide the forward end of the centre-board when it is pulled up, or when it is forced up byits lower edge striking the bottom. The bar or rod E should pass out of the box F, between two rollersG, to prevent friction and wear as the .centre-board is operated. H is a pin passing through the boxA F andboard 'A when the said board is raised up and is not required for use. This construction-and peculiar manner of suspending the centre-board render more of its surface available, give it-more hold upon the water, and consequently make it more effective.

What I claim as new, and desire to secure by Letters Patent, is

The centre-board A, constructed as described, when provided at its forward upper cud with the sliding bar E, by which it is raised or lowered, substantially as herein shown and described.
